Usage

subset_dims(caobj, dims)

Arguments

caobj

A caobj.

dims

Integer. Number of dimensions.

Value

Returns caobj.

Examples

# Simulate scRNAseq data.
cnts <- data.frame(cell_1 = rpois(10, 5),
                   cell_2 = rpois(10, 10),
                   cell_3 = rpois(10, 20))
rownames(cnts) <- paste0("gene_", 1:10)
cnts <- as.matrix(cnts)

# Run correspondence analysis.
ca <- cacomp(cnts)
#> Warning: 
#> Parameter top is >nrow(obj) and therefore ignored.
ca <- subset_dims(ca, 2)
